, particularly to iioor joints for waterclosets.4

The object of the invention is toprovide a tight and durable joint between the metallic soil pipe and the closet bowl of earthenware, porcelain or yother material, and also tof simplifythe work of attaching the same.

Heretofore many schemes have been adopted for securing an air and water-tight connection of the soil pipe with the outlet @passage of the closet bowl, and, in former instances, theuse of putty, white or red lead and similar substances was predominant, which resulted in the connection becoming leakyby reason of decay or disintegration of the material usedin making the joint.

TWhile it is the object of my invention to provide as near an all metallic connection as is possible, it has been found that a hard ce# ment connection between the floor-ring and the bowl outlet is considerably better than a threaded or gasket connection, Aand sucha cement is shown herein to join these parts. FV ith these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be described and particularly pointed out in the appended claim. In the accompanying drawings, Figure 1 is a fragmentary vertical sectional view of a closet bowl connected toa lead soil pipe;

Fig. 2 is a bottom plan view of the bowl out- Fig. 7 Fig. 9 is a sectional view of the metal,

base piece employed in Fig. 7.

Referring more especially to the drawings, and particularly to Figs. 1 to 6, 1 represents the discharge pipe of the `water closet, which is provided with an annular flange, 2,

44, of lead or other suitable material.

having a leri herall de enclin rib, 3, which hidesliheioonnectrion vgith theg soil prilplp,

` e inner circumference of the pipe, 1, adjacent to its outlet opening, is recessed as at 5, to receive the upstanding collar, 6, of the metallic base piece or gasket, 7. This metallic'base piece has projecting wings, 8, and a depending conical collar, 9, whose inner periphery is in alinement with the inner periphery of the collar, 6, and whose outer face is conicalvso as to receive the conical inner face of the ferrule, 10, which is located inside of the pipe 4 and projects slightly above so as to be connected to the floor ring, 11, by solder, 12. This floor ring isprovided with a Vcentral hole to admit the pipe 4, and is beveled off as at 13 to receive the solder, 12. I'preferably provide the ring with a pair of diametrically opposite slots, 14, adapted to `allow the passage of the clamping bolts, 15,

which extend through tubular rivets, 16, and tend to draw the pipe, 4, the ferrule, 10, and

, the iioor ring, 1 1, against the underside of the metallicbase piece, 7, so as to clamp the ferrule, 10, with its concave face into engage- Inentwith the convex face of the collar, 9. The tubular rivets 16 hold the metallic base piece 9 tightly in position upon the outlet pi e 1, and to secure a proper joint, I preferab y insert cement, 17, between the pipe 1 and the collar, 6, so as to insure a thoroughly water and air-tight joint.

In the modification illustrated in Figs. 7 to 9, inclusive, I have shown a bowl outlet pipe, 18, having the usual flange and rib, 19, 20, respectively, adapted to hide the connection of the soil pipe, 21, therewith. In this instance, the metallic base piece, 22, is provided with a conical collar, 23, cemented to the pipe, 18, and held in position thereon by tubular rivets, 24. The ferrule, 25, as used in this instance is similar to that shown in Fig. 6, eXce t that it is carried higher in the pipe, 21, an is adapted to fit the inner surface of the collar, 23. As in Fig. 1, it is secured to the pipe, 21, and to the metal floor ring, 26, by solder, 27, and thefloor ring and pipe are clamped to the metal base piece by bolts, 28,

which pass through the tubular rivets, 24.

be resorted to without departing from the principle or sacricing any of the advantages` of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is:

In a coupling, the combination with an outlet pipe having an annular recess formed in its lower end, a laterally lrecessed flange on said pipe, a gasket having laterally projecting arms, said gasket seated in the annular recess and said arms seated in the lateral recesses in the flange, cement between the pipe and gasket, tubular rivets passing through the arms and vflange to secure the gasket to the pipe, a soil pipe, a ferrule in the end thereof, a iloor ring, means connecting the floor ring to the soil pipe and ferrule, and bolts passing through the 'lloor ring and rivets to secure the ierrule in engagement with the gasket.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
